There are 285 files in /var/lib/glusterd/vols/cluster_data ... including
many files with names related to quorum bricks already moved to a
different path (like cluster_data.client.clustor02.srv-quorum-00-d.vol
that should already have been replaced by
cluster_data.clustor02.srv-bricks-00-q.vol -- and both vol files exist).
Is there something I should check inside the volfiles?
